Sun checked tires

[Fred Hulse]

While at the Q rallyLucas Willemsefound some sidewall cracking on the left side tires that I figure were exposed to the southern sun before I could get my cover and sunshade built,being these and the balance of the 8 tires were but four years old, I was thinking to replace the three that have the sun exposure and replace the balance at the normal seven year life span.
Is there any reason not to do this?
